* lib*/version: Move library version functions into files of their ownAndreas Rheinhardt2022-05-10
| | | | | | | This avoids having to rebuild big files every time FFMPEG_VERSION changes (which it does with every commit). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* swscale: Take the destination range into account for yuv->rgb->yuv conversionsMartin Storsjö2022-02-25
| | | | | | | | | | | | The range parameters need to be set up before calling sws_init_context (which selects which fastpaths can be used; this gets called by sws_getContext); solely passing them via sws_setColorspaceDetails isn't enough. This fixes producing full range YUV range output when doing YUV->YUV conversions between different YUV color spaces. Signed-off-by: Martin Storsjö <martin@martin.st>

* libswscale: Test AV_CPU_FLAG_SLOW_GATHER for hscale functions.Alan Kelly2021-12-21
| | | | | This is instead of EXTERNAL_AVX2_FAST so that the avx2 hscale functions are only used where they are faster.

* swscale/swscale: Fix races when using unaligned strides/dataAndreas Rheinhardt2021-09-19
| | | | | | | | | | | | | | | | | | | | | | | | In this case the current code tries to warn once; to do so, it uses ordinary static ints to store whether the warning has already been emitted. This is both a data race (and therefore undefined behaviour) as well as a race condition, because it is really possible for multiple threads to be the one thread to emit the warning. This is actually common since the introduction of the new multithreaded scaling API. This commit fixes this by using atomic integers for the state; furthermore, these are not static anymore, but rather contained in the user-facing SwsContext (i.e. the parent SwsContext in case of slice-threading). Given that these atomic variables are not intended for synchronization at all (but only for atomicity, i.e. only to output the warning once), the atomic operations use memory_order_relaxed. This affected the nv12, nv21, yuv420, yuv420p10, yuv422, yuv422p10 and yuv444 filter-overlay FATE-tests.

* swscale/utils: Use full chroma interpolation for rgb4/8 and dither noneMichael Niedermayer2021-07-09
| | | | | | | | Dither none is only implemented in full chroma interpolation for these rgb formats Its also a obscure choice (producing less nice images) that implementing it in the other code-paths makes no sense Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* sws: rename SwsContext.swscale to convert_unscaledAnton Khirnov2021-07-03
| | | | That function pointer is now used only for unscaled conversion.
* sws: separate the calls to scaled vs unscaled conversionAnton Khirnov2021-07-03
| | | | | | | | | | Call the scaler function directly rather than through a function pointer. Drop the now-unused return value from ff_getSwsFunc() and rename the function to reflect its new role. This will be useful in the following commits, where it will become important that the amount of output is different for scaled vs unscaled case.

* libswscale/utils.c: Fix bug #8255Gautam Ramakrishnan2020-02-09
| | | | | | | | | | Bug #8255 points out a double free error in libwscale/utils.c file. The double free is because the pointer to cascaded_context of an sw_context is not set to NULL after freeing it. When the sw_context is later freed, sws_freeContext is called on the cascaded_context, causing a double free. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* swscale: Add support for NV24 and NV42Philip Langdale2019-05-12
| | | | | | | | | | | The implementation is pretty straight-forward. Most of the existing NV12 codepaths work regardless of subsampling and are re-used as is. Where necessary I wrote the slightly different NV24 versions. Finally, the one thing that confused me for a long time was the asm specific x86 path that did an explicit exclusion check for NV12. I replaced that with a semi-planar check and also updated the equivalent PPC code, which Lauri kindly checked.

* swscale: Add p016 output support and generalise yuv420p1x to p010Philip Langdale2018-03-02
| | | | | | | | To make the best use of existing code, I generalised the wrapper that currently does yuv420p10 to p010 to support any mixture of input and output sizes between 10 and 16 bits. This had the side effect of yielding a working code path for all yuv420p1x formats to p01x.
